This scatter plot displays the relationship between horsepower and weight for cars from the auto-mpg dataset. The visualization uses d3.scaleLinear to map the data to x and y axes, d3.axisBottom and d3.axisLeft to render the axes with gridlines, and SVG circles to represent each car. The title, axis labels, and tick styling are configured via CSS classes. Data is loaded asynchronously with d3.csv and parsed before being passed to the render function.
